Abstract: A particle image velocimetry system is provided which supplies tracer particles to a flow field around an object (12) from tracer particle supply means, takes an image of reflected light by imaging means (32A, 32B) by irradiating the tracer particles twice with laser light at different times, and determines a velocity vector of the flow field based on the two images obtained of the tracer particles. The two images are each divided into a plurality of test regions, and when first peak value (fp)/second peak value (sp)?1.2 is satisfied by comparison between a first peak value fp and a second peak value sp of a cross-correlation value of a luminance pattern of tracer particles in each test region of the two images, it is determined that the reliability of the velocity vector is high. Thus, it is possible to enhance the precision of measurement of the state of flow by reliably determining erroneous vectors.

Abstract: Systems and methods for determining a customized cosmetic formulation. In one method, a user is guided to capture an image of a skin region with known lighting and color characteristics, and the image is processed to provide calibrated skin color information. A customized cosmetic formulation is automatically determined for the user based on the calibrated skin color information.

The skin region images are processed to provide calibrated skin color information, which is compared to a ground truth data set to identify a set of closest known values in the ground truth data set. A customized cosmetic formulation is automatically determined for the user based on the comparison.

Abstract: A video processing system (10) for automatic license plate recognition (ALPR) provides an interface between video cameras (14, 16) and a host computer (20) through a single high speed USB connection (18). The system (10) supports four simultaneous composite video channels (28A, 28B, 28C, 28D) with two channels dedicated to an IR monochrome video and two channels dedicated to color video. Compression software incorporates a high speed memory for buffering and stripping unnecessary data from a digitized data stream. Monochrome channel data and color channel data are marked with an incrementing index to tag them with frame identification. As a result, processing software in the host computer can re-align the monochrome and color video information after processing a license plate image, regardless of the order of data arrival. Color overview and monochrome recognition images are provided at the same time, and thus show the same plate or vehicle.

Abstract: A moving object detection method and an image processing system thereof are provided. First, a pixel-wise distance of a received image to a reference image is computed to obtain a distance map. A histogram analysis is performed on the distance map to obtain a distance distribution. An entropy value of the distance distribution is computed and a peak distance value which is with a maximum occurrence probability in the distance distribution is searched out. Then, by using a mapping rule, the entropy value and the peak distance value are transformed into a decision threshold value. The decision threshold value is applied in classifying the pixels of the distance map into a group of foreground attributes and a group of background attributes and thereby moving objects in the current image are obtained.

Abstract: A method, a system and a computer device for initiating bi-directional compression of a video stream in a packet switched network, based on delay tolerance of a service or application. A video frame recompression (VFR) utility determines an end-to-end (E2E) delay tolerance retrieved from a Real-time Transport Control Protocol (RTCP) report. The VFR utility then determines the actual expected delay based on a deep inspection of packet headers. The VFR utility utilizes a processing opportunity delay (which determines whether the E2E delay tolerance is greater than the actual expected delay) to reprocess video content comprising Intra-coded (I) pictures/frames and Predicted (P) frames to improve compression efficiency. The VFR utility may also utilize a complexity ratio which is a ratio of the I-Frame rate and the P-Frame rate to select frames for compression. The VFR utility recompresses video content by replacing P-Frames with B-Frames.
